GAS-LAMP EXTINGUSHER.

Application filed February 4, 1969.

make and use the samer` reference being had to the accompanying drawings, and to the figures oit reference marked thereon, which form ak part of this speeitication.

My invention relates to new and usetul improvements in gas light extinguishers and consists of an automatic gas light extin guisher for street lamps.

The object ot' the invention is to provide a simple and reliable cut-oit which is operated in connection with clock mechanism to cut oil' the Vtlow of gas to the burner at any definite time.

My improvements may be applied to any oit the well-known street gas lamps, either ot the antiquated or modern types.

ln the accompanying drawings,-Figure l, is a view of the upper portion et a street lamp ot the more antiquated type, and in which my automatic clock-actuated eut-olil is shown. Fig. 2, is a similar view ot a more modern At'orm oil. street gas lamps lo which my automatic cut-ottA is applied. Fig. 3, is a tace View oli the clock. Fig. l, is a detail View of the upper end ot the lamp post and in which the length of the clocl casing shown. Fig. 5, is a sectional view of a portion ot' the clock mechanism which is directly involved in the cut-oit mechanism.

In a detail description ot the invention, similar reference characters indicate corre sponding parts.

My automatic cut-oft1 device may be convenient-ly applied to any et the well-known street gas lamps. lt may loe placed on the interior ot the globe or exterior thereto and it may be inclosed in any suitable housing. These are mere details which do not necessarily involve the cut-ott devices or their operation. ln the drawings, l have located these cutwof devices in a most conspicuous manner in order that they may be the more readily seen and comprehended. The upper portion of a lamp postof any of the wellknown constructions is shown 'in the drawings to support the removable sleeve portieri Sp eccation of Letters Patent.

amp hy means of suitable arms extendii he'reirom and indicated in the drawings b v VRegardless ot the character of the lampf the cnt-ott devices are practically the same and comprise a valve pin which extends in the path ot' the tlow et gas through the pi 5 to the jet. This pin is extended as at l 4ig t, and has rigidly secured thereto a lever ln the incline position oit this lever as shown in Figs. l and 2, the gas is supplied in one case to the conventional. hnrner and in the other case to the more modern lllelsliach burner. To one end ot' the .lever t3 is attached the end of a suitable cable er chain 8 which attached at its other end to a small grooved pulley l0 which is loose upon an extended portion lll oit the shaft ot the alarm mee" inism ot a clock. The clock is ot' any ot the common types, the mei'fhanism ot which is inelosed in a casing 'l which is sulliported on the upper end ot the lamp post in any suitA able way.

ln the drawings7 l have shown a metallic band T clamped around the upper portion olf the lamp post and to which the clock is altached. The extended portion ol.l the shaft. ll et the alarm meclmnisin has rigidly se cured to ita ratchet wheel i9 which rotates therc\.vith. and :ull'izufent to the outer side. ol' this ralrhot wher-lA the puller lli is' located on said shall l l. fis lie'loreslateil. the pulley l() loose upon said shalt lull maintained in snllicient Ytrictional contact wur; the ratchet wheel l2 to insure the rotation el hoth elements in unison with the shatt li.. This Ytrictional contact between the ratchet wheel and the pulley is maintained. by a spring asher lll which on the outer end 'ot the shaft ll and is held in engagement with the outer side ot the pulley l() hy means ot a nut .i3 which screws onto the outer end oit said shaft. lt will thus he seen that a suiiicient connection between the pulley and the ratchet wheel is rinaintained to insure their moving in unison with the clock mechanism.

'hen it is desired, however, to slaclen the llt) parted to the rachet wheel through the fric- I ratchet wheel adjacent to said pulley, a shaft tion between said ratchet wheel and the pulley. The pawl 15 is pivoted to the end of the clock casing.

The operation of the device will be readily understood: The clock-alarm mechanism is previously set for operation at a prede- .termined time, and the operation thereof causes the shaft 12 to rotate a sufficient distance or extent to actuate the chain 8 and the lever 6, the latter as before stated, beingattached to the extended portion 6 of the cutoff pin. The winding pulley 10 may be reversed after each operation to admit gas to the burner without interfering with any of the attachments. As before stated, the ratchet wheel 12 is fixed to the extended p0rtion 11 of the shaft of the alarm-clock mechanism, but the pawl 15 prevents any reverse movement being imparted to said shaft through the friction between the pulley 10 and the ratchet wheel.

Having described my invention, I claim:

1. In an automatic cut-olf for gas lamps, the combination with a burner tube, a cut-off pin controlling the flow of gas through said tube to the burner, and a lever on an extended portion of said pin, of a chain connected to one end of said lever, a pulley to which the other end of said chain is connected, a

upon which the ratchet wheel is rigidly secured and the pulley is loosely mounted, means for maintaining the pulley in frictional contact with the ratchet wheel to move in unison therewith when the ratchet wheel is rotated with the shaft, and means such as the alarm mechanism of a clock for actuating the shaft.

2. In an automatic cut-off for gas lamps, the combination with a burner tube, a cutolf pin controlling the How of gas through said tube to the burner, and a lever on an extended portion of said pin and through which the pin is actuated to cut off the flow of gas from or admit it to the burner, a chain connected to one end of said lever, a friction device under the control of clock mechanism for actuating said chain to operate the lever to cut ofi' the gas, said friction device being arranged to permit the chain to slacken, and whereby said lever may be actuated to admit the gas to the burner.

In testimony whereof I aiix my signature, in presence of two witnesses.
